Eflite brushless out runner, it's a 32-size and came from a stock scimitar. It's 1010kv and operates on 3-4s, I've seen some people run them on 5s with a slightly smaller prop (9x8 @ 80 amps). Stock setup was a pusher with a 10x8 prop on 4s and gave the 4.5lb plane a nice vertical. This is a higher KV than the power 32 (770kv). Retails 75 from eflites site, asking 40 shipped
